I suspect (not being expert in the serial innards) that with the old
code things would "just work", and the ACPI table bug would never
be noticed.

With the new code, my guess is that the device just wouldn't work
(we think it has an interrupt, but it's not hooked up correctly).

My inclination is that it's better to help find ACPI bugs, and
if broken tables turn out to be a problem, we can add some kind
of command-line switch or blacklist to deal with it. But I
guess we should really get David's opinion, since this is a
potential issue for 2.6 distributions.
